19 Claims.

This invention relates to printing telegraph signal controlled mechanismfor producing perforated tape, and more particularly to the mechanismsauxiliary thereto for feeding out tape during periods of inactivity ofsuch signal controlled mechanisms. The invention is particularlyapplicable to the so-called typing reperforator.

Reperforators as used in teletypewriter service are receivinginstruments which serve to relay messages from one circuit to another.In accordance with the incoming message a tape is perforated and is thenused to retransmit the message. The typing reperforator types thecharacters corresponding to the code punchings on the same tape so thatthe destinations or the contents of the messages can be read quickly.During the code signal controlled operation of the reperforator. thetape advancing means are actuated to advance the tape with eachoperation of the selecting mechanism. Upon the cessation of the signalimpulses it is often necessary or desirable to feed out a considerablelength of the tape for handling, or to clear the end of a messagethrough the tape transmitter if the tape is fed directly into it fromthe reperforator in a continuous piece. For some purposes it is highlydesirable that this tape feed-out be on a noninterfering basis, i. e.,that the tape be fed out without employing or disturbing the receivingmechanism of the reperforator.

The principal object of the present invention is to provide an improvednon-interfering tape feed-out arrangement which will be satisfactory asan auxiliary to reperforators such as the typing reperforator.

Another object of the invention is to provide a manual tape feed-outwhich upon operation will initiate the auxiliary feed-out and uponrelease immediately terminate such feed-out.

Another object of the invention is to provide a manual tape feed-outsuch that it will be effective only during periodsof inactivity of thecode signal receiving mechanism, and upon resumption of activity of suchmechanism control of the tape feed will be promptly returned to thesignal responsive mechanism.

Another object of the invention is to provide an auxiliary arrangementwhich will feed out tape at an abnormal speed.

Another object of the invention is to provide for a manual tape feed-outin response to the operation of a local device and also an automatictape feed-out in response to special signals transmitted from thedistant sending station, and at the same time to provide in either casefor the prompt return of tape feed control to the code signal responsivemechanism upon the resumption of activity of such mechanism.

In accordance with a feature of the invention the return of the controlof the tape fed by the auxiliary feed-out, whether manual or automatic,to the code signal responsive mechanism upon resumption of activity ofsuch mechanism is so rapid that the typing reperforator will receive,print and punch the first character transmitted Without the need ofsending synchronization characters in advance of the messages.

In'accordance with another feature of the invention control of the tapefeed-out may be exercised through the local manually operable device, byremote control from the distant transmitting station or by a manuallyoperable device located at the receiving station but at a point removedfrom the typing reperforator.

In accordance with another feature of the invention, if the tape isbeing fed out in response to the operation of the manual control at thereperforator, the auxiliary feed-out will be terminated by the releaseof the manual control or by the resumption of activity of the signalreceiv ing mechanism, whichever occurs earlier.

These and other objects and features of the invention will be clearlyunderstood from the following description of one desirable embodiment ofthe invention when read with reference to the accompanying drawings, inwhich-.-

Figure 1 shows diagrammatically a part of the receiving mechanism of atyping reperforator;

Fig. 2 shows diagrammatically another portion of the typingreperforator, including the tape punching mechanism, and

Fig. 3 shows diagrammatically and in part' schematically the applicantsnon-interfering tape feed-out mechanism and the associated electricalcircuits.

Likecharacters of reference in the several figures of the drawingsdesignate corresponding parts. The typing reperforator, as is well knownin the art, includes mechanism whereby received current pulses aretranslated to the code bars to position the code bars to type thecharacter called for; at the same time the corresponding codecombination is set up by a mechanical linkage which positions the punchfingers to punch the tape in accordance with the character typed; apunch arm or hammer then drives the punch pins through the tape into a.die block while the corresponding character is typed,

With reference to Fig. l of the drawings, which discloses one unit ofthat part of the receiving mechanism which functions to position thecode bars, the selector magnet controls the position of the armature l2and the armature extentension IS in accordance with the open or closedcondition of the telegraph circuit. It will be understood that themechanism includes six rotating cams so spaced angularly on a shaft thateach will function at the same time that the corresponding signal pulseis being received. When the open start pulse is received the armature I2is released. This operates a latch (not shown) and allows the shaftcarrying the selector cams to start rotating. One of these cams I4 isdisclosed in Fig. 1. The cams are so spaced that at the same time thatthe first of the five pulses of the code signal is being received thefirst cam engages the projection on the code bar operating leverassociated with the first code bar and rotates it slightly in acounterclockwise direction. The effect ofthis movement depends uponwhether or not the magnet armature is operated. If it is operated, themovement of the code bar operating lever |5 (controlled in itsmovementby the spring l6) by the first selector cam l4 lifts up thesword l1 and causes the righthand projection of the upper end of thesword to strike the right-hand end of the armature extension Hi. Thisrotates the sword H in a clockwise direction on its pivot l1, and whenthe selector cam M in its continued rotation clears the code baroperating lever l5 and allows the code bar operating spring IE torestore it to normal position, the point of the sword I1 is brought downagainst the left-hand side of the lever l8, rotating it in acounter-clockwise direction and so moving the code bar |9 to the right.It will be understood that in like manner each of the signal pulses istranslated to the appropriate code bar, and that after all five signalpulses have been received and the code bars properly positioned, thesixth cam releases a clutch and allows the printing mechanism tooperate.

With reference to Fig. 2, disclosing a part of the receiving mechanismhaving to do with the positioning and operation of the punch fingers,the position of the code bar I9 and the position of the code bar lockinglever 20 controlled by the bail 2| determine the position of theselecting finger 26 through the selecting finger linkage. It will beunderstood that there is disclosed only one of the five units of theapparatus for positioning the punch fingers.

It will be noted that the code bar l9 has notches |9 and Hi". When thelocking lever 20 is in notch I9, the code bar is locked in the markingposition; if lever 20 is in notch IS, the mechanism is in the spacingposition; whereas if the lever 20 is as disclosed in the drawing betweennotches l9 and IS, the mechanism is in what is termed the instantaneousintermediate position, to which the lever 20 is restored by the bail 2|as the latter returns to its normal idle position. With reference to thearrows of. Fig. 2, it will be noted that the bail 2| is in its lowerposition and has forced the lever 20 in the direction indicated to bringit to the intermediate position. Thus the levers 20, 22, 23, 24 and 25are positioned as indicated to movethe selecting finger 26 to the right.In this position the raised portion 21 of the finger 26 is interposedbetween the punch bail 29 and the punch pin 28, and when the punchhammer 30 is operated by the actuation-of the punch hammer linkage 3|,the pin 28 will be driven through the tape 32 into the die block 33. Itwill be understood that if the finger 26 is moved to the left, theraised portion 21 will not be between the bail 29 and the pin 28, andaccordingly the operation of the punch hammer would not drive the pin 28through the tape.

It is important in connection with the present invention to note thatwhen the code signal responsive mechanism of the reperforator isinactive bail 2| remains in the position shown in Fig. 2.

It is believed that the disclosures of Figs. 1 and 2, when examinedalong with Fig. 3 which shows the applicants feed-out arrangement perse, will give to the reader skilled in the art sufficient foundation fora full understanding of the invention. Further reference, however, maybe made to the description of the single magnet reperforator found in U.S. Patent No. 1,884,743, issued to Kleinschmidt, October 25, 1932.

With reference to Fig. 3 of the drawings, it will be understood thatduring the normal typing and punching of the typing reperforator themain shaft 34 and the punch cam 35 rotate and cause the regular punchbail 36 to oscillate and operate the punch and tape advancing mechanism(schematically indicated), including the punch hammer 30, whereby thetape 32 is punched in accordance with the incoming message and dulyadvanced with each operation. For a detailed disclosure of the punch andtape advancing mechanism reference may be had to the aboveidentifiedKleinschmidt patent, page 2, line 126 to page 3, line 35.

The present invention as disclosed in one desirable embodiment providesauxiliary means including the shaft 40 and the cam 4| for actuating thelinkage 3| to feed out the tape 32 during periods of inactivity of thecode signal responsive selecting mechanism, a latch 44 which normallyprevents the auxiliary feed-out mechanism from operating, various meansincluding primarily the manual latch release button 45 for releasing thelatch 44, and means whereby the tape feed control will be promptlyreturned to the receiving mechanism of the reperforator upon theresumption of activity of such mechanism.

In addition to the manual control through operation and release ofbutton 45 provision is made in accordance with the embodiment disclosedfor remote control from the distant sending station through theoperation of contacts 64 and 65 associated with the reperforator andalternative control from a point at the receiving station remote fromthe reperforator itself through the operation of the key 13.

It will be noted that the driving shaft 31 is geared to the main shaftat 38 and is associated with the driven feed-out shaft 40 through aclutch 39. Shaft 40 carries a member 42 with which the latch 44 normallyengages. Thus, although the shaft 31 is rotating, the driven feed-outshaft 4!) is normally stationary because latch 44 prevents it fromrotating.

If it is desired to feed out tape,vmanual con trol is exercised at thereperforator by pulling (to the left) the latch release button 45 which,it will be noted, has associated with it a plunger 46 and a plungerextension 41 with a hooked right end. When button 45 is pulled, themember 41 trips the latch 44 and permits the shaft 40 with the feed-outcam 4| to rotate. It is to be noted that the pulling of button 45 opensa contact 48 to disable an electromagnet 49, which if not disabled wouldlock the member 41 in the engaged position. The rotation of the feed-outcam 4! causes the linkage 43 to impart to the punch hammer linkage 3|oscillation of the type normally produced by the main punch cam 35through bail 36. It will be noted that cam 4| has two lobes, and thatthere is thus produced a frequency of oscillation which is higher'thanspecifically twice as high as-the normal frequency. Accordinglyauxiliary apparatus will produce a feeding out of the tape at twice thespeed of the normal tape feed which is under the control of the codesignal responsive mechanism. It will be readily understood that thisabnormal frequency of oscillation and the consequent abnormal speed offeed-out may be provided for by any suitable means, including theadjustment of the gearing. at 38 to drive the shaft 3'! at a higherspeed. When suflicient tape has been fed out, the auxiliary feed-out isterminated by the release of the button 45 and member 41, which permitslatch 44 to re-engage member 42 and stop the rotation of cam shaft 40.

The tape fed out by the applicants arrangement will, if the condition ofthe punch selecting mechanism is as shown in Fig. 2, be punched with theletters character, as will be readily understood from an examination ofthat figure and the discussion of it given hereinbefore. As alreadyindicated, the main bail on the typing reperforator has returned to itsnormal idle position and has restored the code bar locking lever to thenon-locking position. Accordingly the punch selecting levers are in themarking position whatever may be the position of the code bars above thetype basket. Accordingly in the arrangement specifically disclosed theresult of the pulling of the button 45 is the abnormally rapid feedingout of the tape punched with the letters character.

If while the latch release button 45 is operated and tape is being fedout through the operation of the auxiliary mechanism, signaling isrecommenced, the'first mark to space transition on the line will causethe armature of the line relay 5| to move to itsspacing contact (S), anda circuit will be completed from ground through battery 15, thiscontact, the winding of a slow-release relay 52 and contact 55 to thewinding of electromagnet 56. Normally the spacing contact of line relay5| is connected through contact 54 to the regular rectifier balancingload. If, however, button and member 41 have been operated, a member isrotated counter-clockwise and causes the attached spring member 53 toopen contact 54 and close contact 55. electromagnet 56 operates 'as theresult of the operation of button 45, and the subsequent operation ofthe line relay 5| to the spacin position, armature 5'! drives member 58downward to disengage the hooked member 4! and permit latch 44 tore-engage member 42 on shaft 46 and stop the auxiliary feed-out. Becauseof the fact that electromagnet 56 can be operated from the spacingcontact of line relay 5| only when contact has been closed through theoperation of the hooked member 41, the unnecessary operation ofelectromagnet 56 during the reception of a message is prevented. v

' It will be understood from the description given hereinbefore that theapplicants tape feed-out arrangement is strictly non-interfering-i. e..

upon resumption of the activity of the reperfora-' tor the auxiliaryfeed-out control is promptly terminated and control of the tape feed isim- When mediately returned to the code signal responsive mechanism.There will be no interference with the printing and punching of thefirst character of the incoming message because that character is notprinted or punched until after all five selecting pulses of thecharacter have been received. The time interval is at least 132milliseconds at 60-speed operation, and this allows ample time for latch44 to re-engage and terminate the rotation of shaft 40. As indicatedhereinabove, this shaft, in addition to carrying a double-lobe cam suchas 4|, may be driven at any reasonable'and desired speed throughsuitable gearing at 38 to the main shaft.

It should be noted that once the member 41 is disengaged from the latchthrough the operation of electromagnet 56, the feed-out cannot be begunagain through this manual operation until the latch release button 45with its associated members has been restored and re-operated.

In addition to the manual'feed-out control provided at the reperforator,the applicants'a'rrangement provides for tape feed-out by remote controlfrom the sending station. For this purpose there are provided inassociation with the reperforator at the receiving station contacts 64and 65, relays 66 and 61 for controlling the operation of the feed-outelectromagnet 49 and a timing circuit 69-'l0, a gas-filled tube ll andarelay 12 for controlling the operation of the feed-out terminatingelectromagnet 56. It

is believed that these elements and the associatedtion'of the systemwhereby feed-out is effected by remote control.

Contact 64, which may be termed the upper case contact, is normally openand is operated in response to the sending of a designated upper case'character from the transmitting station. On the reception of thepredetermined code sequence, this contact is closed and re-opened duringa part of one operation of the receiving mechanism. Contact 65, whichmay be termed the universal contact, is normally held closedduringthe'idle periods of the receiving mechanism. While the receiver isoperating in response to incoming signals, contact 65 opens and thencloses for a portion of each cycle of operations. The adjustment'is suchthat contact 64 will re-open after contact 65 has closed. The operationof the tape feed-out system, following the reception of a feed-outsequence, is as follows:

The closing of contact 64' completes a circuit through battery 63,contact 62, contact 64, the winding of relay 66 and contact 72", andrelay 66 operates. Contact 65 will open andthen close. Relay 66 looks upover a circuit from ground through contact 12", the winding andright-hand contact of relay 66, contact 65, contact 62 and battery 63.At this point the action stops until the closure of the tape out conWhen contact 68 closes, a circuit is completed through battery 63,contact 62, the left-hand contact of relay 66, contact 68, theright-handl contact and winding'of relay 61, and contact the tapetransmit- 12', and relay 61 operates. The relay is locked in itsoperated Condition over a circuit through contact 12", the winding andright-hand contact of relay 61, the left-hand contact of relay 66,contact 62 and battery 63.

It is to be noted that relays 66 and 61 are both operated and lockedthrough the unoperated contact 12 of relay I2 and that the operation ofrelay 12 will cause the release of relays 66 and 61.

Relay 61 on operation charges condenser 10 through the timing resistor69. It also energizes electromagnet 49 by completing a circuit throughthe winding of the electromagnet, contact 48 (which is closed becauselatch release button 45 is unoperated) the left-hand contacts of relays61 and 66, contact 62, and battery 63.

The operation of electromagnet 49 moves the armature 50 to the left,causing the movement of member 41, the tripping of latch 44 and thestart of the feed-out operation through the rotation of shaft 40. Theoperation of electromagnet 49, as will be clear from examination of Fig.3, also results in the moving to the left of spring member 60 connectedwith the latch mechanism, and the closing of contact 6| and the openingof contact 62 on a make-beforebreak basis. The operation ofelectromagnet 49 does not result in the opening of contact 48 because ofthe back lash between the button 45 and the associated plunger 46,indicated in'Fig. 3. The movement to the left of armature 50 and theassociated spring 53 upon the operation of electromagnet 49 openscontact 54 and closes contact 55, with the result that the connection ofthe spacing contact S of line relay is transferred from the rectifierbalancing resistance (not shown) to the winding of electromagnet 56.

The closure of contact 6| establishes a looking circuit forelectromagnet 49 through contact 48 and battery 63. It also completes acircuit which continues the charging of condenser 10. Relay 61 is lockedup over a circuit through contact 12", the winding and right-handcontact of relay 61, the left-hand contact of relay 61, contact 6| andbattery 63. Relay 66 is now locked up over a circuit including contact12", the winding and right-hand contact of relay 66, contact 65, theleft-hand contacts of relays 66 and El, contact 6| and battery 63.

It will now be clear that, following the operation of electromagnet 49,tape will be fed out until electromagnet 56 operates. This operation maybe brought about in either of two-ways. First, if there is a.mark-to-space transition of line relay 5|, battery 15 will be connectedover the spacing contact, the winding of slow release relay 52 andcontact 55 to the winding of electromagnet 56. The same mark-to-spacetransition will also cause the reperforator receiving mechanism tooperate, opening contact 65 during part of the cycle and releasing relay66. The second way in which the operation of electromagnet 56 may bebrought about is through the operation of relay 12, which will bediscussed hereinafter.

When electromagnet 56 operates, the armature 51 and the member 58 aremoved downward and member 41 is disengaged from the latch 44, allowingthe latch to re-engage the member 42 on the driving shaft 40 andterminate the tape feedout. The operation of electromagnet 56 alsoresults in the closing of contact 62 and the subsequent opening ofcontact 6|. This transfers the locking path of electromagnet 49 back tothe left-hand. contact of relay 61 and the locking path of relay 66 tocontact 65. The last-mentioned contact will open during the ensuingcycle of operations of the reperforator, and relay 66 will release. Thelocking path of relay 61 is likewise transferred to the left-handcontact of relay 66 and will release when relay 66 releases.Electromagnet 49 then releases and all contacts are restored to thenormal unoperated condition. The charging of condenser 10 will beterminated and the condenser will lose any accumulated charge to groundover the winding of electro-' magnet 49, The tape feed-out system is nowidle and will not interfere with the normal operation of thereperforator but may, of course, be re-energized by any one of theseveral actions of applicants arrangement.

Let it be assumed now that relays 66 and 61 are operated, condenser 10is being charged, electromagnet 49 is energized, and the train of leversassociated with latch 44 operated to permit the feeding out of the tape.As condenser 10 is charged an electromotive force is impressed on theplates of the gas-filled tube H until the electromotive force becomesgreat enough to render the tube conductive. It will be understood, ofcourse, that the time required to fire tube 1| depends upon theconstants of the circuit including resistance 69, condenser 10, battery63 and After the lapse of the predetermined time from the operation ofrelay 61, the operation of electromagnet 49 and the start of the feedoutoperation, tube becomes conductive, condenser IO discharges through thetube and the winding of relay I2, and the last-mentioned relay operates.On its operation relay 12 locks up through its left-hand contact,contact 6| and battery 63. The operation of relay 12 opens its contact12 and releases relays 66 and 61. The operation also closes contact 12and completes the circuit through the winding of electromagnet 56, withthe result that latch 44 is re-engaged with the member 42 and the tapefeed-out is terminated. As has been described hereinbefore in connectionwith the feed-out termination following the mark-to-space transition ofthe line relay 5|, this latch operation closes contact 62 and openscontact 6|. Thus the locking path for electromagnet 49 is transferred tothe left-hand contact of relay 61, which opens. The electromagnet isthen released with the consequent restoration of the feed-out system toits idle condition.

It remains to describe another feature of the applicants arrangement asspecifically disclosed whereby the auxiliary tape feed-out may be begunin response to a manual operation which may occur at the receivingstation but at a point removed from the reperforator. This control iseffected by the momentary operation of the nonlocking key 13, whichcloses contact 14 and momentarily shorts the upper case contact 64. Itwill be understood that the completion of this short circuit has thesame effect as the closing of .contact 64 in response to the receptionof the upper case character impulses and the circuit will operate asdescribed hereinbefore to cause the auxiliary tape feed-out. It will benoted that the winding of the slow release relay 52 is in series withthe spacing contact S of line relay 5|. This arrangement serves toprevent the initiation of a feed-out operation by key 13 while signalsare being received. The release time of relay 52 should be at leastone-sixth second for 60-speed operation.

The manual release key 16 may be operated to close a contact 1.1 andthus effect the termination of the auxiliary feed-out operation or toerase the effect of the operation of relay B6. The key may also be usedas an emergency stop of the tape feed-out in case of circuit trouble,
